Apple’s Retail Customer Service Approach
A - Approach the customer with a “warm welcome”
P - Position, Permission, Probe — Tell the customer what you want to do, ask permission, and then ask them questions to determine their needs.
P - Present the appropriate product solution that fits their needs.
L - Listen to their concerns.
E - End with a fond farewell and an invitation to return.
You could even use this as a framework for creating customer service emails.
